4.8/5
Beast Below is a high-volatility underwater pokie from Hacksaw Gaming, built on 5 reels, 4 rows, and 14 fixed paylines. The main appeal is its moody presentation and expanding Siren wilds that carry multipliers up to 200x. During testing the base game ran slow, with most wins landing below the stake and the free spins staying out of reach.
The volatility sits at 4 out of 5, so long quiet spells are part of the deal. My biggest takeaway is simple: the artwork carries this game further than the gameplay does. The verdict below lands as a conditional recommendation, strong for atmosphere lovers and weak for action seekers.
I played Beast Below in demo mode on desktop across 100 spins, about 12 minutes of play. I started with a 5,000-credit bankroll and used a 1-credit bet the whole way.
I focused on base-game feel, win frequency, the expanding Siren wilds, and bankroll movement. I did not trigger the free spins and did not test the Bonus Buy or mobile play, so those areas are flagged rather than judged.
Beast Below is a gorgeous, high-volatility pokie that asks for patience most casual players won’t have. The base game felt slow, the wins were mostly small, and the free spins never arrived across my session. The expanding Siren wilds were the highlight and hint at the bigger payouts waiting in the bonus.
Beast Below felt like a classic high-volatility pokie where I found most of the value was locked inside the free spins. **I also found that the RTP isn’t the same at every casino. Beast Below can run at 96.29%, 94.27%, 92.25% or 88.28%, depending on which version the casino uses, so I’d always check the in-game information screen before playing.** Across my 100 spins, I counted about 25 wins, but most were small and often paid less than my stake.
I found the pace slow, and I spent most of the session waiting for the bonus rounds to bring some real excitement. Because I needed three FS scatters to trigger the free spins, the bonus felt distant during my run. The base game was slow in my opinion, especially through the longer stretches without a meaningful hit.
The expanding Siren wilds were what broke up those quieter periods for me. When I landed a Siren as part of a win, it expanded up the reel and applied a multiplier. I found those moments were easily the best source of excitement in the base game while I waited for the free spins.

Playing Beast Below is a patient, quiet experience broken up by short bursts from the Siren wilds. The base game ran slow for me, with long stretches where very little happened on the reels. Even the winning spins rarely felt like wins, because most paid less than my 1-credit stake.
Win frequency looked reasonable on paper at roughly 25 hits in 100 spins, but the size of those wins is what mattered. Small returns kept nudging the balance down instead of holding it steady. By the halfway point I was already down about 40 credits, and the drift never really reversed.
The emotional rhythm of Beast Below leans on anticipation rather than action. Each spin builds toward the free spins you’re hoping to trigger, so the bonus does a lot of the heavy lifting for engagement. When the free spins stay away, the base game has to carry the session on its own, and that’s where it struggled for me.
The expanding Siren wilds were the bright spots. When a Siren landed and helped complete a line, it expanded up the reel with a multiplier, turning a few otherwise ordinary wins into better ones. The animation on those moments is genuinely lovely and gave the quiet run some life.
Still, the overall feel was a game more interesting to look at than to grind. A few times I honestly considered switching to something with more happening. To me, the base game didn’t feel worth playing.
This snapshot uses a fixed 5,000-credit bankroll, a flat 1-credit bet, and 100 spins in demo mode. It shows how Beast Below moved across a single high-variance run without a bonus trigger.
Early on, the best moment arrived fast. On spin 12 a Siren Wild landed on the central reel, expanded to cover the whole reel, and applied a 4x multiplier to a regular combo for a 2.8x win. That was the high point of the entire session.
Through the middle, the balance drifted down steadily. By the halfway mark the bankroll was off by about 40 credits, with small wins failing to keep pace with the dead spins. The free spins never came close, since only two FS scatters landed once across the run.
Late in the session the pattern held, and Beast Below finished on 4,912 credits after 100 spins. That’s a loss of under 2% at a 1-credit bet, which is a soft landing for a high-volatility pokie that never hit its bonus.
The core of Beast Below is a classic left-to-right pokie: match three or more paying symbols across 14 fixed paylines from the leftmost reel. The lift comes from the expanding Siren wilds, which are the game’s defining mechanic. Sirens can land at any time in the base game.
When a Siren can help form a win, it expands up to the top of its reel and brings a multiplier of 2x up to 200x. If more than one Siren joins a win, their multipliers are added together before being applied. During testing, the Siren wilds were where the meaningful base-game wins came from, including the session’s best spin.
Beast Below keeps a tight feature set, and the expanding wilds do most of the work. The Siren wild is the base-game feature, expanding up the reel with a multiplier when it completes a win. This was the only feature that triggered often during my 100 spins.
The Siren’s Call free spins round is triggered by three FS scatter symbols and awards 10 free spins, with a climbing Pink Siren and extra scatters adding more spins. The Down Below free spins round is triggered by four FS scatter symbols and introduces the expanding Diver symbol. I did not trigger either round, so I can’t describe how they pay from first-hand play.
A Bonus Buy is also available for players who want to jump straight to the free spins. Autoplay is listed as a feature for Beast Below, though its availability can vary by operator, device, and jurisdiction. Beast Below runs on a random number generator, and Hacksaw Gaming is a licensed provider whose titles use certified RNGs, but game-specific independent certification for Beast Below could not be verified from a primary source.
Beast Below has a default RTP of 96.29% according to the Hacksaw Gaming game data. Operators can also run lower configurations of 94.27%, 92.25%, or 88.28%, so the active percentage can vary by casino. Always check the game info panel before real-money play, because a lower version changes long-run returns.
Against the wider market, a 96.29% default sits around the industry average for online pokies. The lower 88.28% version, by contrast, falls well below what most players would want. That gap between versions matters more here than the headline figure alone.
In practice, the high 4-out-of-5 volatility means the RTP concentrates in the free spins rather than the base game. My session showed the base-game side of that math: many small wins, no bonus, and a slow bleed. A low outcome looks like a long dead run that drains a bankroll before the free spins trigger.
An average outcome resembles my run, ending down under 2% with the balance drifting rather than swinging. A strong outcome depends on triggering the free spins and stacking Siren or Diver multipliers, which is where the big returns live. RTP describes the long run, not any single session, so short results will vary widely.
Beast Below advertises a maximum win of 10,000x your stake. That ceiling comes from stacking expanding Siren and Diver multipliers, each worth up to 200x, inside the free spins rounds. It is a real number, but it is a rare best case rather than a session target.
Most players will never see anything close to 10,000x, and my session is a fair illustration. My biggest win was 2.8x the bet, and I never even entered a bonus round across 100 spins. The base game alone has no realistic path to the top payout.
To approach the max win, you need to trigger the free spins, land multiple high-value multipliers, and have them combine on strong lines. That chain of events is uncommon by design in a high-volatility pokie. Treat the 10,000x figure as the top of the range, not an expectation for your bankroll.
Beast Below offers a Bonus Buy that lets players pay to enter the free spins directly. I did not use the Bonus Buy during this session, so I can’t judge its cost, expected value, or fairness from first-hand testing. Given how distant the free spins felt in the base game, the Bonus Buy will tempt players who mainly want the bonus, but I’d want to test it before saying whether it’s worth the price.
Beast Below is a high-volatility, bonus-dependent pokie, so bankroll planning matters more than usual. At small stakes the balance drains slowly, but dead spells stack up while you wait for the free spins. At higher bets that same drift becomes a much faster drop.
A sensible approach is to bring enough balance to ride long dry runs and keep stakes modest so a cold streak doesn’t end things early. The biggest mistake is chasing the bonus by raising bets during a dead spell, which can empty a bankroll fast. Patience is the price of admission with Beast Below.
I found Beast Below a good fit if you value story, unique graphics, and a calming but eerie atmosphere. I also think it suits patient high-volatility players who are comfortable with the variance while waiting for a shot at the free spins. If presentation matters as much as payouts, I think Beast Below is worth a try.
I wouldn’t recommend Beast Below if you want frequent wins, regular bonuses, and something happening on almost every spin. I also found the dead spells could be frustrating if you’re playing with a smaller bankroll. I’d skip it if you want constant action and regular payouts.
The closest competitor is Wanted Dead or a Wild from Hacksaw Gaming, another feature-led, high-variance title with the same studio polish. For players who want more frequent action than Beast Below offers, a lower-variance pokie with steadier base-game hits is the better alternative. Beast Below rewards patience, while a lower-variance game rewards regular play.
For a higher-risk alternative, Nolimit City titles such as Fire in the Hole push volatility further than Beast Below does. For a lower-volatility alternative, an atmosphere-led slot with more frequent base-game wins will suit players who found Beast Below’s dead spells too long.
